Kaai and Soraa already working up Blu-ray successor?

Simmer down -- it's not like you haven't seen advancements in blue laser technology before, and even though the current format war may still be raging when either's successor rolls into town, Kaai and Soraa are already looking to the future. Reportedly, Khosla Ventures has invested in both of the aforementioned firms, and while company representatives aren't disclosing much at the moment, we do know that the duo is exploring ways to "exploit gallium nitride, which is also the basis for existing blue LEDs and blue lasers." Apparently, they'd like to concoct suitable replacements for conventional LEDs in the lighting market and make a showing in the optical data storage arena, too. But seriously, with 200GB Blu-ray discs, who needs to worry about the next best thing?
